Hire director / personal Ruby on Rails developers

A passionate Ruby on Rails developer, author of i Love Ruby https://i-love-ruby.gitlab.io/ I am a person who can build projects on a turn key basis. I completely agree with 37Signals philosophy of developing software. I agree with Rails 100% including the way it enables us to build modern web apps with Hotwire. I am constantly looking for ways to develop applications with perfection and with less of cognitive load for developers. I love to build high performance teams for your business, and keep them mentally healthy so that we have an honest work place where people are free to tell facts.

I’ve always been fascinated by the intersection of creativity and technology. My coding journey began when I discovered how a few lines of code could transform an idea into a fully functioning application. From that point on, I was hooked: I poured countless hours into experimenting with everything from Ruby on Rails to more modern JavaScript frameworks. Over the years, I’ve refined my skills and found my passion in building clean, maintainable systems that put user experience first. One of my proudest earliest accomplishments involved leading a small team to develop a custom internal tool that automated a tedious data-entry process. Seeing the hours of manual work drop to just a few minutes was incredibly rewarding—it reminded me why I love being a developer in the first place. I’m constantly seeking new ways to grow: whether that’s diving into emerging technologies, improving my testing strategies, or exploring new coding paradigms, I believe there’s always more to learn. Above all, I thrive on solving tricky problems in ways that others might not have considered. I love collaborating with designers, project managers, and fellow developers to turn concepts into polished products. I bring a unique blend of empathy, curiosity, leadership and technical expertise that helps me bridge communication gaps and ensure every project is set up for success. Helping teams build something truly meaningful is what drives me—and I’m excited for what comes next.

I'm a full-stack Rails developer with experience building robust, scalable products, whether as a Ruby monolith or with TypeScript/ReactJS frontends. I've been working with Rails for over 10 years (since version 3.x) and have specialised in creating and maintaining codebases that are easy for teams to read, understand, and maintain. Key to those goals are: using standardised code styles (ensuring RuboCop and the team's practices are perfectly aligned) writing well-structured, easy-to-understand and fast tests constructive and collaborative code reviews ensuring documentation, from git histories to READMEs and other materials (online and offline) records useful, meaningful information that can be easily kept up to date and in sync with any code changes I've recently been adding GraphQL to my skill set, which also includes PostgreSQL, ElasticSearch, Redis and other languages (Swift, PHP, JavaScript, and more). On the front end, I have experience with both Rails' native toolset and ReactJS, Next.js, and React Native. I also have experience with platform-native toolsets, such as SwiftUI, to deliver applications that feel intrinsically part of the user’s mobile experience. I've worked on projects of various sizes, from scheduling and booking software for a major tech training company to systems that enable TV distributors to sell thousands of hours of programming worldwide. Ideally, I'm looking to work on products with which I can feel personally invested – an exciting product or tech-for-good project would definitely suit me better than a fintech role.

I'm Patrick, a backend developer with over 17 years of hands-on experience building web apps with Ruby on Rails—across startups, NGOs, and large enterprises alike. From launching social platforms in Thailand to building insurance portals in Germany, I've worn many hats: freelancer, CTO, and senior engineer. What drives me is crafting robust, maintainable systems that solve real-world problems. I’ve worked on e-commerce shops, benefit platforms, mobile apps, and even refugee registration systems in South Sudan—always with a focus on clean architecture, fast iterations, and reliable delivery. I thrive in complex environments where others might hesitate: legacy codebases, scaling systems, domain-driven design, or integrating with obscure APIs. If your team needs someone to bring order to the chaos—or just ship that one gnarly feature no one wants to touch—I’m your guy. I'm currently based in Hamburg, but remote-friendly and happy to plug into teams anywhere Rails is loved.

I am passionate about helping first-time founders navigate the complex world of software development. My approach focuses on discovering, planning and building the MVP that lets you to validate your concept, raise money, or get your first paying customers quickly while assisting you with establishing the long-term roadmap of your product. My 25 years of experience in software development span three countries and fields as varied as online banking, text messaging, politics, logistics, e-commerce and sports facility management. I've been technical lead, co-founder, CTO and independent consultant, building and shipping product every day by myself or with small teams, from one-person shops to VC-backed scale-ups with successful IPOs and private exits. What sets me apart is my commitment to making myself replaceable. I create maintainable, well-documented code as well as automated testing, deployment and monitoring practices that make it easy to bring development and operations in-house when you’re ready. My goal is to provide maximum value at every stage while setting you up for independence and long-term success. My preferred technical stack is Ruby on Rails (with Hotwire Native for mobile), which empowers me to build and ship fully functional, well-tested and feature-rich apps within a few weeks (or sometimes days).

Hi ... I'm Francis. With a background in Electrical and Electronics engineering, I have worked in fast paced startups over the last 6 years to build and scale applications that are not only purposeful and maintainable but also evolve to leverage new tech and trends. Recently, I worked to architect and implement two mobile app applications and web apps all powered with Rails and integrating AI in search, recommendation and extraction areas. This has helped them get to a level of personalization that beats competitors and increased our retention rates by over 30%. Whether you are seeking a team lead, CTO, or a driven and adaptable backend or frontend engineer to join your team, I am a highly capable and experienced professional ready to make a lasting impact. Over my years in engineering, I have learnt that conventions only take you so far, experimenting with the new, the different and the niche often moves the needle in business and can be what makes a customer stay. This has inspired me to venture into ViewComponent, Plex and even AI to see what can be improved or done different to surpass the customer requirements using Rails and related stacks. Having worked with various platforms including AWS, GCP, HuggingFace and more, I am always willing to learn and keep chipping at hard problems and leveraging what exists to build solve business and engineering problems. I look forward to chatting about your busines and how my skills and expertise can be of value to your team, clients and business objectives. My skills of interest in this domain include: Ruby on Rails, TailwindCss, HotWire and Stimulus, React, Bootstrap, JQuery, Heroku, AWS, GCP, Azure, HuggingFace, DevOps, MongoDB, PostgresQL and more.

Hey, I’m Ale 👋 I’m a software engineer with over 15 years of commercial experience helping companies bring ambitious products to life. I’ve been a first hire, a tech lead, and everything in between. I’ve worked with founders and CTOs, helping them go from zero to one, scaling platforms, and running high-stakes systems. I’ve shipped code across finance, logistics, e-commerce, healthcare, esports, automotive, edtech, and even fashion industries. Recently, I’ve focused on helping companies like Blitz, Canary, and Superkind to integrate AI into real-world products. My core stack is Ruby on Rails and Elixir/Phoenix, but I have also shipped great-quality code in Node, React, and Python apps. I care about clean code, quick feedback loops, and solving the correct problems to maintain a sustainable release cycle. Great code shipped today, beats beautiful code shipped two weeks later. For the past 8 years, I’ve worked remotely with US-based teams, writing code, leading teams, reviewing PRs, and pairing up to solve tricky bugs. More about me, projects, companies I've worked for, and pretty much everything I've done so far over here: https://alemiralles.dev/ Thanks for looking at my profile, and have a great one!

Seasoned code wrangler with over a decade in Ruby on Rails and a past life as a social worker and policy researcher. I've got a knack for translating geek speak for humans and wrangling stakeholder needs into delighted users and maintainable code. Looking to land in a place where code meets impact. Full stack developer that has spent over a decade in the Ruby/Rails ecosystem. I lean ops to backend, but I can get in there and wrangle JS components and CSS if need be. I often wear at least a little bit of a product manager hat, have been a team lead on large projects, and I even try to remember to write documentation and technical briefs. I'm longwinded in slack, shy in person, didactic and friendly in code reviews, and occasionally down a rabbithole. Loves: Wrangling weird bugs and annoying APIs, refactoring, clear code (for the humans) and good tests (for the robots), figuring out the best places to deliver maximum impact and shipping quickly, teaching myself new things, compassionate communication and collaboration with multiple stockholders, making weird things happen in the CI pipeline Special superpowers: T-shaped generalist that still geeks out on learning new things, sniffing out something that isn't a problem yet but definitely will be (and I don't mean premature optimization), care a lot about readable code. Worked as a social worker for a decade, there's more soft skills than people might think in getting software out the door. Not so loves: JS in general, jerks, arrogance, watching junior developers not get the support they need and thinking it is their fault, refreshing staging for an hour wondering why my debugger isn't getting hit. -- Have worked in startups at all stages of their life cycle as both an introverted grumpy solo developer and team leader, helped make product decisions, mentored other developers, deleted prod a few times, etc. I chafe a bit at schedules, but occasionally I'll figure out a big that would have been a big problem in the future at 3am and just fix it. Love fixing those things. I can meeting during normal human hours though. -- Open to short and long term contracts and FTE for the right fit. Prefer chill flat organizations where everyone likes and respects each other and just gets stuff done. I've shipped features faster at those organizations than any that were focused on relentless hustle. -- Tell me why you believe in your tech and I'll tell you about one of my weird side projects like a Led Zeppelin button or a confessional that floats in the air. -- Have PhD level statistics classes buried in my brain somewhere, know my way around python and some data analysis, have built ETL pipelines - if it has to be done, I'll try to figure out a way to get it done. And the longer you hang around this world, you realize the most important programming language is being able to talk to people in kind and useful ways. -- Senior enough to know that sometimes it's the code you don't write that solves the problem ;) Junior enough to still get excited every time I make LEDs blink with magic words.

I am a passionate technical expert, software craftsman, entrepreneur and mentor. I offer hands on experience in solving business problems, making software, and building engineer- ing teams that make software. I analyze business needs and take on the responsibility of ensuring strategically significant business results. I practice, implement and lead using proven software engineering techniques to ensure quality, accelerated delivery of working software.

I’m a senior developer and product strategist with 10+ years building custom software, mostly with Ruby on Rails. I turn complex problems into fast, scalable solutions—and I always build with the end user (and the business) in mind. I got into dev through entrepreneurship—building tools to run my own businesses. That mindset never left. I think like a founder, move fast, and care deeply about results. Lately, I’ve been focused on integrating AI into products: • Automating workflows with tools like OpenAI, Make.com, and LangChain • Building AI-powered features that enhance user experience and drive growth • Helping SaaS teams use AI to scale smarter without adding headcount I’ve led everything from zero-to-one builds to product turnarounds, working closely with founders and small teams. I thrive in fast-moving environments where priorities shift and speed matters. When I’m not building software, I’m in the mountains snowboarding, hiking, or chasing the next great view. Let’s connect if you need someone who can think strategically, code fast, and actually ship.
